C++ WIN32 程序 ,从屏幕输入数据然后给WCHAR 数组赋值

 1     char lingshi_sBuf[20] = { 0 };
 2     cout << "输入测试项目" << endl;
 3     cin.get(lingshi_sBuf, 20);//输入字符串，当输入是Enter键时结束输入
 4     cout << "当前项目为：" << lingshi_sBuf << endl;
 5     //获取输入缓存大小

41     memcpy(&g_block_data_name[0], &lingshi_dBuf[0], 2);//tick
42     memcpy(&g_block_data_name[1], &lingshi_dBuf[1], 2);//tick
43     memcpy(&g_block_data_name[2], &lingshi_dBuf[2], 2);//tick
44     memcpy(&g_block_data_name[3], &lingshi_dBuf[3], 2);//tick
45     delete lingshi_dBuf;

以上代码,应该还有内存泄漏的问题
